COKE-OVEN APPLIANCE.

SPECIFICATION forming part of Letters Patent No. 781,213, dated January 31, 1905.

Application filed July 26, 1904-.. Serial No. 218,229.

To all whom t may con/cern..

Be it known that I, HEINRICH KorPERs, a citizen of the German Empire, and a resident of Rellinghauserstrasse 40, Essen-on-the-Ruhr, Germany, have invented certain new and useful Improvements in Top Appliancesv to Coke- Ovens, of which the following is a specification.

My invention relates to a compensation-joint connecting the gas-main on top ofl a coking plant with the standpipe;.-and its object is to provide a communication between the said gas-main and stand-pipe in which certain disadvantages adhering to the devices hitherto in use are avoided. The rigid valve hitherto recesses, specially in those' atthe bottom ofA the stand-pipe, endeavors to remove the hard material Vresulting frequently in a breakage of the cups. ,Moreoven the absence of a closing device renders an inspection after removal of the connecting-elbow difiicult.

advantages are obviated by the construction shown on the drawings herewith, in which- Figure l is'a full viewof my device, and Fig. 2 a vertical section of the same. Fig.3 is a detail viewv of. the pipe-.jointhereinafter mentioned. Fig. 4 is a plan view of my improved construction, and Fig. 5 the same view ing of the elbow by hand, and is made tight y by a dry seal ofv grooves. The other end of the said elbow is provided with a water seal and is connected with the gas-main by a short tube g, which comprises a cup 7L, receiving an annular foot t' of the said elbow c, which has a lmale tubular end lo inserted in the opening 4of the said short tube, thus permitting a dripping of any iuid pitchy matter only beneath the said water seal.` lThe said short tube ghas at its bottom a similar tubular end Z,"prov jecting into the gas-mainf. The said tubular end may be closed by a basin or trough m, held by a rod a inra guide or passage 0. The said trough may be given the position indicated in Fig. 1 by dotted lines to serve as a receiver'of the fluid tar dripping from the aforesaid tubular ends lo Z, or it may be adjusted so as to assume the position shown in full lines in Figs. l and 2, and will i-n this case, together with the said tubular end Z, act as a fluid-matter seal and at the same time shut oif the gas-main f from the outside when the elbow c is lifted or turned aside. Now the hot gases passing through the stand-pipe a will cause an expansion of the latter, raising the elbow c, which finds its support in the short tube g, while the ball-and-socket-lilre arrangeyment of its other end permits a free rotary movement without impeding the tightening of the said stand-pipe against the outside nor its regular support. The gases coming through the stand-pipel pass through the elbow c, the tar carried along collecting mainly in the basin-receiver or trough m in the gas-main.

When it is desired to inspect the inside of the gas-main of an oven not in operation or remove the tar collecting in the aforesaid receiver, the latter will have to be given the position indicated by full lines in Figs. l and 2, which is done by means of the rod n in the guide 0 aforementioned. The elbow-tube may now be easily lifted and turned aside in the spherical joint without breakage of the cups or other injury. The receiver closes the gasmain tight against any influx from outside, and the tar may be easily dippe'd out.

Hitherto water was notV used for sealing purposes vin the gas-ttings on coke-ovens because it evaporates rapidly in high temperature and the customary construction of -the seal on the stand-pipe was not proof against l any dropping back into the oven of the prod-y ucts of condensation.- Practice has shown,

IOO

the absence of the said water seal.

tirely excluded. The condensation near the water seal of the admixtures fioating in the very hot gases brought about by the escape of heat is by the above-described construction not only rendered inoffensive to the passage of the gases, but at the same time the said construction only makes the aforesaid basin m under all circumstances an efficient closure. Thus there will always be present quite independent of the temperature of the gases a quantity of fluid suiiicient for sealing purposes, the cooling effects of the said water seal preventing a revaporation of the contents of the receiver m, which would occur in Only the quantity of water used for a permanent renewal of the evaporated fluid varies, but can be easily regulated.

The stand-pipe being as above set forth supplied with a dry stuffing and the only liquid seal being provided beyond the turn of the gas-current brought about by the aforesaid elbow c a dropping back of the products of condensation into the oven cannot take place. The triiiing admixture of steam with the gases is of no consequence.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim isl. The combination with the standpipe having the cup-shaped'top member and the gasmain, of an elbow compensation-joint provided with loops or handles, one foot of the said elbow terminating in a semispherical journal member resting in the cup-shaped top member of the said stand-,pipe and having circular grooves and the other end of the elbow terminating in a short tube and connected with vand supported by the gas-main substantiall y as described.

2. The combination with the stand-pipe having the cup-shaped top member and the gasmain having a gas-inlet in shape of a short tube end with a water seal at its upper edge and with shut-oil means at the lower edge, of an elbow compensation-joint provided with loops or handles, one foot of the said elbow terminating in a semispherical journal member resting in the cup-shaped top member of the said stand-pipe and having circular grooves and the other end of the elbow terminating in a tubular male end insertedinto said tube cnd of the gas-main, substantially as described.

3. In combination, a stand-pipe having a cup-shaped top member, a gassmain having` a gas-inlet in shape of a short tube end with a water seal at its upper edge, its lower edge freely projecting into the gas-main, a basin or trough receiver adjustable by means of a rod in a suitable guide adapted to seal said short tube at its lower end and an elbow compensation-joint provided with loops or handles, one foot of the said elbow terminating in a semispherical journal member resting in the cupshaped top member of the said stand-pipe and having circular grooves and the other end of the elbow terminating in a short tube and connected with and supported by the gas-main substantially as described.

In testimony whereof I have hereunto signed my name in the presence of two witnesses. HEINRICH KOPPERS.
